I am pretty new to all of this and before I did something stupid I wanted to ask for some feedback. I was going to build a version of the Bedair ball turner and then starting looking at the boring head versions and decided that was much simpler for what I needed to do. This will be for Aluminum 90% of the time.
I bought a 2" Shars boring head set with a 3/4" shank and I have a boring bar mount for the BXA QCTP which has a 1" hole with a 3/4" collar for smaller bars. The boring head shank fits very nice in that collar. The shank it is threaded on the end so I plan to simply screw a bolt through a larger end cap which will hold my handle. I was looking at what I have to do this and the largest steel stock I have is 1-1/4". I have some black delrin that is I believe 2" which I thought could also work well as it has very little friction.
So my dilemma is I see a few options:
1: Use the steel 3/4" collar and buy steel to use on the back end to mount the handle (I think the 1-1/4" may be a bit small). I will still probably cut 2 delrin washers for between the QCTP holder and boring head and back side and the holder.
2: Use the 3/4" collar and use the Delrin on the back side to hold the handle and create a delrin washer between the boring head and holder.
3: Create a single Delrin piece that is the 3/4" collar and back side for holding the handle as one piece. Still create a delrin washer for between the boring head and holder.
I realize the Delrin is not as strong as the steel, but I am not sure it matters that much in this scenario. Am I crazy for thinking of just using the Delrin and making a one piece holder that will fit in the boring bar holder?
Some pics of what I have. I had the holder the wrong way, but you get the idea.
Thanks!
